PURPOSE: It is known that work stress was linked to WRMDs in workplace. The purpose of this study was to identify the characteristics of work related musculoskeletal disorders (WRMDs) related to job stress among prosthetists and orthotists. METHODS: Eighty-six self-reported symptoms of discomfort (SRSD) and job stress were collected by questionnaire and analyzed. RESULTS: The results were as follows: Over 70% of respondents had WRMDs. The shoulder was the most painful region and each of "within 15 minutes", "once a week" and "severe moving or doing exercise" items were main characteristics in the SRSD. Finally, the "repetition of simple work" item in job stress ranked as resulting in "often discomfort" in over 43% of respondents. Additionally, there was a statistically significant correlation between job stress and pain intensity (p<.05, $r_s$=.36). CONCLUSION: Further studies are needed to identify the factors affecting musculoskeletal symptoms and job stress of prosthetists and orthotists in Korea.

Occupational musculoskeletal disorders currently account for the largest proportion of the occupational illnesses in Korea. In this research, status of musculoskeletal disorders among the occupational illnesses was examined through workers' compensation claims data. Types and characteristics of musculoskeletal disorders were looked at other data set as well. The data sets included epidemiological investigation data reported by Occupational Safety and Health Research Institute, and data collected from occupational disease surveillance reports and Korean occupational health-related scientific journals. Number of cases, incidence rate and insurance benefits for occupational musculoskeletal disorders in Korea are increasing every year. In addition, musculoskeletal disorders occurrence is shifted from large enterprises group to small-and-medium group, from manufacturing to service sector, and from production workers to office and professional workers. Although low back pain is still most common, its occurrence characteristics is gradually shifted from traumatic to cumulative while musculoskeletal disorders are somewhat seemingly moved from lumbar to upper limb body part. Musculoskeletal disorders were observed to be more diverse and prevalent in epidemiological investigations or surveillance data rather in workers' compensation claims data. Musculoskeletal disorders occurrence is related to demographic factors, occupational psychosocial factors, and ergonomic risk factors at workplace for which appropriate preventive measures needed to be made accordingly.

Musculoskeletal disorders show symptoms of pain and dysfunction caused by accumulation of minute damage on nerves and blood vessels which are related to specific body parts. This is more likely to occur in the elderly. In Korea, 40.3% of the agricultural population is over 65 years old. In these cases, the portion of musculoskeletal disorders is more than 80% in acute/chronic diseases related to agricultural work. Therefore, measures for physical health care and safety prevention of elderly farmers are needed. In this study, we intend to propose a method to measure musculoskeletal health condition through the motion recognition device and VR contents. For this, we analyze the agricultural work causing musculoskeletal disorders of farmers, and suggest a motion analysis algorithm that can measure the health condition of the musculoskeletal system. In addition, we are going to propose a training method customized for farmers on the basis of VR contents in order to prevent musculoskeletal disorders.

This study aimed to examine the general characteristics of individual workers, psychosocial working environment, and ergonomic risk factors which affect the status of musculoskeletal disorders. Self-report was carried out for musculoskeletal symptoms and ergonomic risks in working environment in 856 production workers in 16 small to medium sized manufacturing companies. Musculoskeletal symptoms were examined with a standardized questionnaire, and ergonomic risks were evaluated with a qualitative self-administered instrument for the tasks related to musculoskeletal disorders. Major findings were as follows: 1) Complaint rate for musculoskeletal symptoms was higher in female, aged, married workers with longer working hours, less leisure/hobby activity, longer household working hours and history of disease or accident. 2) Complaint rate for musculoskeletal symptoms was significantly higher in workers with dissatisfaction, difficult tasks, and no self-control at work. 3) Complaint rate for musculoskeletal symptoms was significantly higher in workers involved in tasks with major ergonomic risk factors, and handling heavy equipment. 4) Explanatory power increased the model with the musculoskeletal symptoms as dependent variable and demographic variables, psychosocial working environment and ergonomic risk factors included, and total explanatory power of 18.6% revealed the significant effect. Based on the results, we can conclude that musculoskeletal symptoms in manufacturing workers are associated with individual demographic characteristics, psychosocial working environment and ergonomic risk factors.

The main purpose of this study was to investigate relationship between WRMD (Work Related Musculoskeletal Disorders) symptoms and dangerous factors in medical technologistes who work in Gwang-ju city and Jeollanam-do province. Experimental group was 74 medical technologistes at hospital centers, hospitals, general hospitals, university hospitals. From the this survey, we found that significant statistical difference in WRMD symptoms by general characteristics (sex, exercise) and working environmental characteristics (examination numbers, time of margin, repetition, intensity of work, time of using PC). In the general factors, Odds ration in male vs female, do exercise vs do not exercise were 4.557 (95% CI=1.003-20.713), 2.747 (95% CI=0.59-12.783). In working environment factors, Odds ration in little of examination numbers vs a lot of examination numbers, little of time margin vs a lot of time margin, non repetitive vs repetitive, non intensity of work vs intensity of work, little of pc using time vs a lot of pc using time were 1.901 (95% CI=0.828-4.363), 1.15 (95% CI=0.335-3.944), 3.952 (95% CI=1.095-14.262), 1.411 (95% CI=0252-7.891), 2.606 (95% CI=1.055-6.437) respectively. For prevention of WRMD symptoms, Most of hospitals should improve medical technologists of working circumstances, especially control a intensive of work, working speed and guarantee enough break time. Therefore, This study suggests that increasing workers and examination of automation, streching during working be needed.

One of the methods being suggested as a way to address social issues is the utilization of big data analysis techniques. In this study, we utilized keyword network analysis and CONCOR analysis techniques to analyze the research trends on work-related musculoskeletal disorders. The findings of this study are as follows: Firstly, the number of papers on work-related musculoskeletal disorders has been consistently increasing, with an average of over 33 articles published per year since the investigation of musculoskeletal risk factors in 2003. The publication rate showed an increase from 2007 to 2009. Secondly, the frequency of the top keywords identified through text mining were as follows: work (4,940), musculoskeletal disorders (2,197), symptoms (1,836), related (1,769), musculoskeletal system (1,421). Thirdly, the CONCOR analysis resulted in the formation of four clusters: ' Musculoskeletal disorder treatment', 'Occupational health and safety management', 'Work environment assessment', and ' Workplace environment measurement'. It is expected that this study will contribute to the development of research on musculoskeletal disorders and provide various directions for future studies.

This study examined the effects of the symptoms of musculoskeletal disorder and the burden of the body on work stress in a university hospital workers. The research surveyed 679 subjects. The relevant factors affecting the job stress were found to be female, young people age group, unmarried, shift work, work more than 8 hours, short experience workers. The work stress was significantly higher in the non-smoker (p=0.000), regular exercise/sports(p=0.022) and non-drinking(p=0.038) groups. In addition, the mental fatigue, presence of musculoskeletal symptoms, fatigue level, and marital status increase the risk of the work stress. The results showed that the burden of the body and musculoskeletal disorders are related interactively with each other.

Ergonomic intervention techniques were adopted to assess and control potential risk factors of work-related musculoskeletal disorders(WMSDs) in the automated light assembly manufacturing system. Ten different kinds of assembly workstations implemented with a conveyor system and twelve female workers were observed and evaluated with careful video film analysis. Several close examinations using sets of checklists established by qualified safety and health organizations, such as NIOSH, OSHA, and ANSI, were conducted and every workers and staffs in the site participated in the self-report questionnaires and off-line interviews. Typical risk factors and symptoms of the upper extremity musculoskeletal disorders were found and categorized into specific parts of body. To reduce risk factors of WMSDs and improve system productivity new revised workstation standards, physical dimensions, were suggested accordant with anthropometric characteristics of workers and a heuristic decision strategy of rotating shift work schedules according to work contents has proposed to mitigate cumulative physical stress. Finally, ergonomic programs of entire company to prevent WMSDs were structured.

The aim of this study was to investigate musculo-skeletal symtoms and working conditions of university library's librarians to search for the risk factors related to musculo-skeletal symptoms. The study subjects were 266 librarians who were working at 20 university libraries. A self-recording questionnaire was used to investigate the general characteristics, working conditions, job intensity, job satisfaction and stress, education of musculoskeletal disorders and nature of musculoskeletal symptom. Statistical analysis was done by using t-test and multiple regression analysis. The complaint proportion of self-reported positive musculoskeletal symptoms was 62.5% and that of severe musculoskeletal symptoms was 26.1%. Multiple regression analysis showed that low satisfaction of working conditions, high job intensity, irregular mealtime, job stress were closely related to the positive rate of musculoskeletal symptoms. Therefore, it will be necessary to make efforts to reduce the prevalence of musculoskeletal disorders improving working conditions and mitigating the job intensity.
